In this work, oximes of 1-(2-pyridyl)tridekane-1-one and 1-(4-pyridyl)tridecane-1-one were used as model hydrophobic extractants for iron(III) from a chloride media. Both studied pyridyl ketoximes have the ability to extract iron(III) from chloride solutions. The highest degree of iron(III) extraction was observed for 1-(2-pyridyl)tridecane-1-one oxime. During extraction with 4-pyridyl ketoxime, a precipitated complex was observed, which has a disadvantageous effect for the extraction process. Iron(III) could be effectively stripped by 1% HCl from organic solution after extraction. Selectivity extractions from multielemental aqueous solutions containing iron(III) using 2- and 4-pyridyl ketoximes were also studied. The highest extraction percentage and good selectivity was observed for Cu2+ from a solution containing 1.0M Cl- with 1-(2-pyridyl)tridecane-1-one oxime. A scheme of separation of particular metal ions from mulielemental aqueous solutions was also proposed. The separation of metal ions is possible in three stages of extraction.
